All patients completed a comprehensive questionnaire survey and underwent abdominal ultrasound examination and a blood test. NAFLD was diagnosed using ultrasonography after other etiologies were excluded. Logistic regression and restricted cubic spline model were conducted to evaluate the relationship of UHR with NAFLD risk.Results The multivariable adjusted odds ratio(95% confidence interval, CI) for NAFLD in the highest versus lowest quartile of UHR was 3.888(2.324–6.504). In analyses stratified by sex and age, we observed significant and positive associations between UHR and the risk of NAFLD in each subgroup. In analyses stratified by body mass index(BMI), a significant and positive association was found only in individuals with a BMI of ≥ 24 kg/m2. Our dose-response analysis indicated a linear positive correlation between UHR and the risk of NAFLD.Conclusion UHR is positively associated with the risk of NAFLD and may serve as an innovative and noninvasive marker for identifying individuals at risk of NAFLD.展开更多

Methods: The patients who were treated in the Department of Cardiovascular Medicine of our hospital from January to December 2022 were selected as the study subjects, and the high risk and extremely high risk groups of grade I, II and III hypertension were selected for comparative analysis to explore their clinical significance. Results: There was a statistically significant difference in the number of patients with extremely high risk of grade II hypertension between men and women (P 0.05), which showed that there was no specificity in the concentration detection of serum uric acid and cystatin C in different grades of hypertension;there was no significant difference in serum uric acid concentration between grade II and grade III of hypertension with high risk grade and cystatin C concentration between grade I and grade III of hypertension with high risk grade (P > 0.05), but there was significant difference in the concentration detection of serum uric acid and cystatin C between the other groups (P < 0.05), which indicates that the detection of serum uric acid and cystatin C has important clinical significance in the high risk degree of hypertension. Conclusion: In the comparison of the detection of blood uric acid and cystatin C in different levels of hypertension with extremely high risk, the difference of cystatin C in grade I and grade III was not statistically significant, and the rest were statistically significant;therefore, the detection of serum uric acid and cystatin C can provide reliable laboratory data for clinical diagnosis and treatment of the extremely high risk degree of different levels of hypertension.展开更多

Initial absorbance of the reaction mixture before uricase action (A0) was obtained by correcting the absorbance at 293 nm measured before the addition of uricase solution, and background absorbance (Ab) was predicted by an integrated method. Uric acid concentration in reaction solution was calcu-lated from ?A, the difference between A0 and Ab, using the absorptivity preset for uric acid. This kinetic uricase method exhibited CV<4.3% and recovery of 100%. Lipids, bilirubin, hemoglobin, ascorbic acid, reduced glutathione and xanthine <0.32 mmol/L in serum had no significant effects. ?A linearly responded to 1.2 to 37.5 μmol/L uric acid in reaction solution containing 15 μl serum. The slope of linear response was consistent with the absorptivity preset for uric acid while the intercept was consistent with that for serum alone. Uric acid concentrations in clinic sera by different uricase methods positively correlated to each other. By Bland-Altman analysis, this kinetic uricase method accorded with that by quantifying the total change of UV absorbance on the completion of uricase reaction. These results demonstrated that this kinetic uricase method is reliable for serum uric acid assay with enhanced resistance to both xanthine and other common errors, wider range of linear response and much lower cost.展开更多

It’s still debatable whether it’s an independent risk factor or it’s just a consequence of other disorders associated with cardiovascular diseases like hypertension, diabetes and dyslipidemia. Objective: The aim of our study is to elucidate whether in patients with heart failure serum uric acid level correlates with left ventricular ejection fraction supporting the possibility that the detection of progressive hyperuricemia in these patients may be an indicator of deteriorating cardiac function. Methods: We conducted a prospective study that included 124 studied patients and 26 apparently healthy persons at Coronary care unit and Internal Medicine Department at Sohag University Hospitals. Studied populations were classified into;* Group “I”: newly diagnosed heart failure, * Group “II”: decompensated heart failure on regular treatment, * Group “III”: decompensated heart failure but stopped their treatment from three months, Group “IV”: control group, healthy and age-matched subjects. We studied the association between left ventricular ejection fraction, the severity of congestive heart failure and the serum uric acid levels and the well-known conventional risk factors. Results: The main finding was the significantly higher mean serum uric acid levels in patients with congestive heart failure versus apparently healthy persons with “P value = 0.02”. When we adjusted the serum uric acid with other significant risk factors in the univariate analysis which were age, gender and smoking, serum uric acid was an independent risk factor “P value = 0.04”. There was a significant correlation between serum uric acid level and the severity of congestive heart failure “P value 0.35”. High rates of serum uric acid levels were recorded in patients with reduced ejection fraction. A uric acid level of 8.45 mg/dl was found to be the most appropriate cut-off point with the sensitivity 62% and the specificity 78.5%. Conclusion: Higher serum uric acid levels are significantly correlated with the severity of congestive heart failure and left ventricular ejection fraction. Serum uric acid is an independent risk factor for congestive heart failure.展开更多

This study enrolled 122 patients including 63 women (51.6%). The mean age was 55.9 ± 10.6 years (range 30 to 74 years). Obesity weight was found in 38 cases (31.1%) of which 20?were men (33.9%) and 18 women (28.6%). Abdominal obesity was found in 104 cases (85.2%). The average serum uric acid in patients with obesity weight was 63.3 ± 18.9 mg/L vs 62.4 ± 14.2 mg/L for no-obese patients (p?= 0.63). The average serum potassium in obese patients was 4.06 ± 0.42 mEq/L vs 4.02 ± 0.46 mEq/L for no-obese (p?= 0.65). The average GFR was 73.4 ± 21.4 ml/L in obese patients vs 66.6 ± 22.6 ml/min in no-obese (p?= 0.03). The LVH was found in 81 cases (66.4%). The LVH was found in 65 (62.5%) obese patients vs?16 (88%) non-obese patients (OR = 4.8, 95% 1.04?-?22?p?= 0.02). Only abdominal?obesity has been correlated with left ventricular hypertrophy after multivariate analysis. Emphasis must be focused on public health actions for effective and appropriate measures against obesity and hypertension, whose prevalence is increasing in our region.展开更多

Methods We investigated the association between serum uric acid levels and the risk of prevalent cardiometabolic diseases, 10-year Framingham risk for coronary heart disease, and 10-year risk for atherosclerotic cardiovascular diseases(ASCVD) among 8,252 participants aged ≥ 40 years without diabetes from Jiading district, Shanghai, China. Results Body mass index, waist circumference, blood glucose, glycated hemoglobin, blood pressure, and serum lipids increased progressively across the sex-specific quartiles of uric acid(all P trend < 0.05). Compared with individuals in the lowest quartile, those in the higher quartiles had a significantly higher prevalence of obesity, hypertension, and dyslipidemia(all P trend < 0.05). A fully adjusted logistic regression analysis revealed that individuals in the highest quartile had an increased risk of predicted cardiovascular disease compared with those in the lowest quartile of uric acid. The multivariate adjusted odds ratios(ORs) [95% confidence intervals(CIs)] for the highest quartiles for high Framingham risk were 3.00(2.00-4.50) in men and 2.95(1.08-8.43) in women. The multivariate adjusted ORs(95% CIs) for the highest quartile for high ASCVD risk were 1.93(1.17-3.17) in men and 4.53(2.57-7.98) in women. Conclusion Serum uric acid level is associated with an increased risk of prevalent obesity, hypertension, dyslipidemia, 10-year Framingham risk for coronary heart disease, and 10-year risk for ASCVD among Chinese adults without diabetes.展开更多

However, its prognostic value in acute ST-segment elevation myocardial infarction (STEMI) is still uncertain. The aim of this study was to evaluate the prognostic value of SUA on admission in patients with STEMI undergoing primary percutaneous coronary intervention (PPCI). Methods: We prospectively enrolled 150 STEMI patients underwent PPCI. The mean age of the studied population was 56.1 years, 78%?were males?while 22% were females. Patients were divided into tertiles based on the basal serum uric acid level. Patients with high SUA (n = 72) was defined as a value in the third tertile (>6.4 mg/dl), and a low SUA group (n = 78) was set as a value in the lower two tertiles ( Results: SUA level on admission carried prognostic value in patients with STEMI undergoing PPCI where the low uric acid group had better KILLIP class (P =0.001), better TIMI flow (P = 0.001), higher ejection fraction (49.53 ± 8.75 versus 39.95 ± 7.06;P =0.001), better survival and lower incidence of other major adverse cardiac events (MACE) (P = 0.01) during the hospital stay and three months follow up?than the high uric acid group. Age, SUA > 6 mg/dl, TIMI flow, Killip class and EF 40% were independent predictors for MACE in such patients. Conclusions: High SUA level on admission was associated with higher frequency of in-hospital and three months follow up MACE in patients with acute STEMI undergoing PPCI.展开更多

文摘Objective The aim of this case-control study was to explore the association between serum uric acid to high density lipoprotein cholesterol ratio(UHR) and the risk of nonalcoholic fatty liver disease(NAFLD) in Chinese adults.Methods A total of 636 patients with NAFLD and 754 controls were enrolled from the Affiliated Hospital of Qingdao University, China, between January and December 2016. All patients completed a comprehensive questionnaire survey and underwent abdominal ultrasound examination and a blood test. NAFLD was diagnosed using ultrasonography after other etiologies were excluded. Logistic regression and restricted cubic spline model were conducted to evaluate the relationship of UHR with NAFLD risk.Results The multivariable adjusted odds ratio(95% confidence interval, CI) for NAFLD in the highest versus lowest quartile of UHR was 3.888(2.324–6.504). In analyses stratified by sex and age, we observed significant and positive associations between UHR and the risk of NAFLD in each subgroup. In analyses stratified by body mass index(BMI), a significant and positive association was found only in individuals with a BMI of ≥ 24 kg/m2. Our dose-response analysis indicated a linear positive correlation between UHR and the risk of NAFLD.Conclusion UHR is positively associated with the risk of NAFLD and may serve as an innovative and noninvasive marker for identifying individuals at risk of NAFLD.

文摘BACKGROUND The incidence and mortality of liver cancer are among the highest of all malignant tumors in China.The high recurrence rate after conventional hepatectomy is worrying.There is a lack of effective prognostic indicators for liver cancer.AIM To explore the clinical significance of preoperative serum oxidative stress and serum uric acid(UA)levels in hepatitis B-related liver cancer.METHODS The medical records of 110 hepatitis B-related liver cancer patients who under-went hepatectomy in Gansu Provincial Hospital were retrospectively analyzed.Recurrence in patients within 3 years after surgery was determined.The logistic regression model and Pearson or Spearman correlation were used to analyze the correlation between oxidative stress level and UA,and the recurrence of hepatitis B-related liver cancer.RESULTS Compared with the non-recurrence group,the levels of superoxide dismutase(SOD)and glutathione(GSH)in the recurrence group were lower and the levels of malondialdehyde(MDA)and UA were higher(all P<0.05).UA,SOD,MDA,and GSH were risk factors for postoperative recurrence in hepatitis B-related liver cancer patients(P<0.05).UA was positively correlated with MDA(r=0.395,P<0.001)and negatively correlated with GSH(r=-0.204,P=0.032).The area under the receiver operating characteristic curve(AUC)of SOD,MDA,GSH,and UA in predicting the prognosis was 0.276,0.910,0.199,and 0.784,respectively(all P<0.001).CONCLUSION The preoperative serum SOD,GSH,MDA,and UA levels had significant predictive effects on postoperative recurrence of hepatitis B-related liver cancer.
文摘Objective To evaluate the association between serum uric acid(SUA)and kidney function decline.Methods Data was obtained from the China Health and Retirement Longitudinal Study on the Chinese middle-aged and older population for analysis.The kidney function decline was defined as an annual estimated glomerular filtration rate(e GFR)decrease by>3 mL/min per 1.73 m^(2).Multivariable logistic regression was applied to determine the association between SUA and kidney function decline.The shape of the association was investigated by restricted cubic splines.Results A total of 7,346 participants were included,of which 1,004 individuals(13.67%)developed kidney function decline during the follow-up of 4 years.A significant dose-response relation was recorded between SUA and the kidney function decline(OR 1.14,95%CI 1.03-1.27),as the risk of kidney function decline increased by 14%per 1 mg/d L increase in SUA.In the subgroup analyses,such a relation was only recorded among women(OR 1.22,95%CI 1.03-1.45),those aged<60 years(OR 1.22,95%CI 1.05-1.42),and those without hypertension and without diabetes(OR 1.22,95%CI 1.06-1.41).Although the dose-response relation was not observed in men,the high level of SUA was related to kidney function decline(OR 1.83,95%CI 1.05-3.17).The restricted cubic spline analysis indicated that SUA>5 mg/dL was associated with a significantly higher risk of kidney function decline.Conclusion The SUA level was associated with kidney function decline.An elevation of SUA should therefore be addressed to prevent possible kidney impairment and dysfunction.
文摘Objective: To explore the clinical significance of serum uric acid combined with cystatin C detection in high risk degree of hypertension of different grades. Methods: The patients who were treated in the Department of Cardiovascular Medicine of our hospital from January to December 2022 were selected as the study subjects, and the high risk and extremely high risk groups of grade I, II and III hypertension were selected for comparative analysis to explore their clinical significance. Results: There was a statistically significant difference in the number of patients with extremely high risk of grade II hypertension between men and women (P 0.05), which showed that there was no specificity in the concentration detection of serum uric acid and cystatin C in different grades of hypertension;there was no significant difference in serum uric acid concentration between grade II and grade III of hypertension with high risk grade and cystatin C concentration between grade I and grade III of hypertension with high risk grade (P > 0.05), but there was significant difference in the concentration detection of serum uric acid and cystatin C between the other groups (P < 0.05), which indicates that the detection of serum uric acid and cystatin C has important clinical significance in the high risk degree of hypertension. Conclusion: In the comparison of the detection of blood uric acid and cystatin C in different levels of hypertension with extremely high risk, the difference of cystatin C in grade I and grade III was not statistically significant, and the rest were statistically significant;therefore, the detection of serum uric acid and cystatin C can provide reliable laboratory data for clinical diagnosis and treatment of the extremely high risk degree of different levels of hypertension.

文摘Objective The relationship between serum uric acid(SUA)levels and glycemic indices,including plasma glucose(FPG),2-hour postload glucose(2 h-PG),and glycated hemoglobin(HbA1 c),remains inconclusive.We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population.Methods The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study.A total of 105,922 community-dwelling adults aged≥40 years underwent the oral glucose tolerance test and uric acid assessment.The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models.Results A total of 30,941 men and 62,361 women were eligible for the current analysis.Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels,but with different inflection points in men and women.The thresholds for FPG,2 h-PG,and HbA1 c for men and women were 6.5/8.0 mmol/L,11.0/14.0 mmol/L,and 6.1/6.5,respectively(SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices).Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes,while the inflection points were reached earlier in men than in women.
文摘BACKGROUND Gouty tophus is rarely reported in the head and neck areas.To the best of our knowledge,this is the first report on multiple gouty tophi in the head and neck with normal serum uric acid(SUA)levels.CASE SUMMARY We report a case of multiple gouty tophi in the nasal dorsal and auricle regions with normal SUA levels.The patient was admitted to the hospital with a chief complaint of recurrent nasal swelling and pain for 3 years,which was aggravated for 3 d.The patient’s SUA level had been regularly reviewed in the outpatient department and had been successfully controlled for several years.Resection of the nasal masses was performed.Cartilage from the right ear cavity was used to repair the nasal defects.The pathological report confirmed a nasal gouty tophus.No recurrence or deformity was found after a 1 year follow-up.CONCLUSION Normal SUA cannot completely negate the diagnosis of gouty tophus,especially in some rare regions.
文摘BACKGROUND:Few studies investigated serum uric acid levels in patients with acute STelevation myocardial infarction(STEMI).The study was to assess the clinical value of serum uric acid levels in patients with acute ST-elevation myocardial infarction(STEMI).METHODS:Totally 502 consecutive patients with STEMI were retrospectively studied from January 2005 to December 2010.The level of serum lipid,echocardiographic data and in-hospital major adverse cardiovascular events(MACE) in patients with hyperuricemia(n=119) were compared with those in patients without hyperuricemia(n=383).The relationship between the level of serum uric acid and the degree of diseased coronary artery was analyzed.All data were analyzed with SPSS version 17.0 software for Student's t test,the Chi-square test and Pearson's correlation coefficient analysis.RESULTS:Serum uric acid level was positively correlated with serum triglyceride level.Hyperlipidemia was more common in hyperuricemia patients than in non-hyperuricemia patients(43.7%vs.33.7%,P=0.047),and serum triglyceride level was significantly higher in hyperuricemia patients(2.11±1.24 vs.1.78±1.38,P=0.014).But no significant association was observed between serum uric acid level and one or more diseased vessels(P>0.05).Left ventricular end-diastolic diameter(LVEDd) was larger in hyperuricemia patients than in non-hyperuricemia patients(53.52±6.19 vs.52.18±4.89,P=0.041).The higher rate of left systolic dysfunction and diastolic dysfunction was discovered in hyperuricemia patients(36.4%vs.15.1%,P<0.001;68.2%vs.55.8%,P=0.023).Also,hyperuricemia patients were more likely to have in-hospital MACE(P<0.05).CONCLUSIONS:Serum uric acid level is positively correlated with serum triglyceride level,but not with the severity of coronary artery disease.Hyperuricemia patients with STEMI tend to have a higher rate of left systolic dysfunction and diastolic dysfunction and more likely to have more in-hospital MACE.
文摘[Objectives]To evaluate whether the level of serum uric acid in patients with bipolar disorder type I in their manic episode was different from that in healthy subjects,and to evaluate whether the level of serum uric acid is related to the severity of manic episode and the improvement of clinical symptoms.[Methods]A total of 70 patients with bipolar disorder type I in their manic episode were selected,their serum uric acid levels were measured at the beginning of the enrollment and at the end of the first,second and third week,and the clinical symptoms were evaluated with Young Mania Rating Scale(YMRS).65 healthy subjects were enrolled,and their serum uric acid levels were measured only at the beginning of the enrollment.[Results]The level of serum uric acid in patients with bipolar disorder type I in their manic episode was higher than that in healthy adults(t=8.153,p=0.039).At the end of the third week,the YMRS score and uric acid level of the patients were lower than those of the patients at the beginning of the enrollment(t=17.107,p=0.000;t=35.864,p=0.000).[Conclusions]The level of serum uric acid in patients with bipolar disorder type I in their manic episode was higher than that in healthy subjects,and the decrease of serum uric acid level may be related to the improvement of clinical symptoms.

文摘A patented kinetic uricase method was evaluated for serum uric acid assay. Initial absorbance of the reaction mixture before uricase action (A0) was obtained by correcting the absorbance at 293 nm measured before the addition of uricase solution, and background absorbance (Ab) was predicted by an integrated method. Uric acid concentration in reaction solution was calcu-lated from ?A, the difference between A0 and Ab, using the absorptivity preset for uric acid. This kinetic uricase method exhibited CV<4.3% and recovery of 100%. Lipids, bilirubin, hemoglobin, ascorbic acid, reduced glutathione and xanthine <0.32 mmol/L in serum had no significant effects. ?A linearly responded to 1.2 to 37.5 μmol/L uric acid in reaction solution containing 15 μl serum. The slope of linear response was consistent with the absorptivity preset for uric acid while the intercept was consistent with that for serum alone. Uric acid concentrations in clinic sera by different uricase methods positively correlated to each other. By Bland-Altman analysis, this kinetic uricase method accorded with that by quantifying the total change of UV absorbance on the completion of uricase reaction. These results demonstrated that this kinetic uricase method is reliable for serum uric acid assay with enhanced resistance to both xanthine and other common errors, wider range of linear response and much lower cost.

文摘Objective The purpose of this study was to determine the serum uric acid levels and the prevalence of hyperuricemia among Chinese adults in 2015 and compare the differences between urban and rural areas,as well as the differences between eastern,central,and western regions.Methods A national representative sample of 180,208 participants were included using a stratified,multistage,and random sampling method.The demographic characteristics and blood samples were collected to determine the serum uric acid levels and prevalence of hyperuricemia among subgroups using complicated sampling weight.A t-test or ANOVA was used for normally-distributed data.The Kruskal-Wallis rank test was used for skewed-distributed data.The Mantel-Haenszel chi-square test was used to compare the difference in categorical variables.Results The weighted mean uric acid level in Chinese adults was 310.4μmol/L(317.5μmol/L in urban areas and 302.9μmol/L in rural areas).The weighted average values of uric acid in eastern,central,and western China were 315.5μmol/L,303.5μmol/L,and 310.4μmol/L,respectively.The weighted prevalence of hyperuricemia in Chinese adults was 14.6%,with a prevalence of 16.5%in urban areas and12.5%in rural areas.The weighted prevalence of hyperuricemia in eastern,central,and western China was 16.0%,12.5%,and 14.8%,respectively.Conclusion The uric acid level in Chinese adults is relatively high.Effective actions are warranted to improve this metabolic abnormality.
文摘Background: One of the risk factors of congestive heart failure that still under investigations is hyperuricemia. It’s still debatable whether it’s an independent risk factor or it’s just a consequence of other disorders associated with cardiovascular diseases like hypertension, diabetes and dyslipidemia. Objective: The aim of our study is to elucidate whether in patients with heart failure serum uric acid level correlates with left ventricular ejection fraction supporting the possibility that the detection of progressive hyperuricemia in these patients may be an indicator of deteriorating cardiac function. Methods: We conducted a prospective study that included 124 studied patients and 26 apparently healthy persons at Coronary care unit and Internal Medicine Department at Sohag University Hospitals. Studied populations were classified into;* Group “I”: newly diagnosed heart failure, * Group “II”: decompensated heart failure on regular treatment, * Group “III”: decompensated heart failure but stopped their treatment from three months, Group “IV”: control group, healthy and age-matched subjects. We studied the association between left ventricular ejection fraction, the severity of congestive heart failure and the serum uric acid levels and the well-known conventional risk factors. Results: The main finding was the significantly higher mean serum uric acid levels in patients with congestive heart failure versus apparently healthy persons with “P value = 0.02”. When we adjusted the serum uric acid with other significant risk factors in the univariate analysis which were age, gender and smoking, serum uric acid was an independent risk factor “P value = 0.04”. There was a significant correlation between serum uric acid level and the severity of congestive heart failure “P value 0.35”. High rates of serum uric acid levels were recorded in patients with reduced ejection fraction. A uric acid level of 8.45 mg/dl was found to be the most appropriate cut-off point with the sensitivity 62% and the specificity 78.5%. Conclusion: Higher serum uric acid levels are significantly correlated with the severity of congestive heart failure and left ventricular ejection fraction. Serum uric acid is an independent risk factor for congestive heart failure.
文摘The authors conducted a retrospective study over a period of 6 months in a hypertensive population in order to determine the correlation between serum uric acid on glomerular filtration rate (GFR) and estimated serum potassium with left ventricular hypertrophy (LVH) and obesity. This study enrolled 122 patients including 63 women (51.6%). The mean age was 55.9 ± 10.6 years (range 30 to 74 years). Obesity weight was found in 38 cases (31.1%) of which 20?were men (33.9%) and 18 women (28.6%). Abdominal obesity was found in 104 cases (85.2%). The average serum uric acid in patients with obesity weight was 63.3 ± 18.9 mg/L vs 62.4 ± 14.2 mg/L for no-obese patients (p?= 0.63). The average serum potassium in obese patients was 4.06 ± 0.42 mEq/L vs 4.02 ± 0.46 mEq/L for no-obese (p?= 0.65). The average GFR was 73.4 ± 21.4 ml/L in obese patients vs 66.6 ± 22.6 ml/min in no-obese (p?= 0.03). The LVH was found in 81 cases (66.4%). The LVH was found in 65 (62.5%) obese patients vs?16 (88%) non-obese patients (OR = 4.8, 95% 1.04?-?22?p?= 0.02). Only abdominal?obesity has been correlated with left ventricular hypertrophy after multivariate analysis. Emphasis must be focused on public health actions for effective and appropriate measures against obesity and hypertension, whose prevalence is increasing in our region.

文摘BACKGROUND Uric acid is the end product of purine metabolism.Previous studies have found that serum uric acid(SUA)levels are associated with the total cancer risk.However,due to the dual effect of uric acid on cancer,the relationship between the SUA levels and most specific-site cancer remains unclear.AIM To investigate the associations between the SUA levels and incidence of hepatobiliary-pancreatic cancer.METHODS In this prospective cohort study,444462 participants free of cancer from the UK Biobank were included.The SUA levels were measured at baseline,and the incidence of hepatobiliary-pancreatic cancer was determined by contacting the cancer registry.The hazard ratios(HRs)and 95%confidence intervals(CIs)between the SUA levels and hepatobiliary-pancreatic cancer were investigated using multiple adjusted Cox regression models adjusted for potential confounders.RESULTS In total,920 participants developed liver,gallbladder,biliary tract or pancreatic cancer during a median of 6.6 yrs of follow-up.We found that the HR of pancreatic cancer in the highest SUA group was 1.77(95%CI:1.29-2.42)compared with that in the lowest group.After stratifying by gender,we further found that SUA was associated with an increased risk of pancreatic cancer only among the females(highest quartile vs lowest quartile HR 2.04,95%CI:1.35-3.08).Among the males,the SUA levels were positively associated with the gallbladder cancer risk(highest quartile vs lowest quartile HR 3.09,95%CI:1.28-7.46),but a U-shaped association with the liver cancer risk was observed(P-nonlinear=0.03).CONCLUSION SUA is likely to have gender-specific effects on hepatobiliary-pancreatic cancer.High SUA levels are a risk factor for pancreatic cancer in females and gallbladder cancer in males.A U-shaped association with the liver cancer risk was identified.

文摘Objective To determine whether elevated serum uric acid(UA)levels are associated with type 2 diabetes diagnosed using Hb A1 c levels among Chinese adults.Methods We conducted two population-based cross-sectional studies in Qingdao in China in 2006 and 2009.A total of 6894(39.4% men)subjects aged 35-74 years were included in the data analysis.Newly diagnosed diabetes was defined as Hb A1 c level of ≥6.5%,and prediabetes was classified as Hb A1 c level between 5.7% and 6.4% according to the International Diabetes Federation criteria.Multivariate logistic regression was employed to assess the association between UA and prevalence of type 2 diabetes defined using Glycated hemoglobin A1c(Hb A1 c levels.Results Subjects with prediabetes had higher UA levels than those with normal glucose tolerance,newly diagnosed diabetes,and known diabetes,with corresponding values of 325.1(82.5)μmol/L,310.9(84.2)μmol/L,291.3(81.7)μmol/L,305.2(83.6)μmol/L,respectively(P<0.001 for all comparisons).Binary logistic regression analysis showed that UA was a possible predictor for the prevalence of type 2 diabetes diagnosed using Hb A1 c levels,and the second quartile of UA levels had a higher odds ratio(OR:4.088;95% CI:2.900-5.765)for Hb A1 c than the other quartiles after adjusting for age,body mass index,sex,marital status,education,income,alcohol consumption,smoking,and cardiometabolic parameters.Conclusion Serum UA is significantly associated with type 2 diabetes diagnosed using Hb A1 c levels,independent of other cardiometabolic parameters.

文摘Objective To examine the association between serum uric acid levels and cardiovascular disease risk among individuals without diabetes. Methods We investigated the association between serum uric acid levels and the risk of prevalent cardiometabolic diseases, 10-year Framingham risk for coronary heart disease, and 10-year risk for atherosclerotic cardiovascular diseases(ASCVD) among 8,252 participants aged ≥ 40 years without diabetes from Jiading district, Shanghai, China. Results Body mass index, waist circumference, blood glucose, glycated hemoglobin, blood pressure, and serum lipids increased progressively across the sex-specific quartiles of uric acid(all P trend < 0.05). Compared with individuals in the lowest quartile, those in the higher quartiles had a significantly higher prevalence of obesity, hypertension, and dyslipidemia(all P trend < 0.05). A fully adjusted logistic regression analysis revealed that individuals in the highest quartile had an increased risk of predicted cardiovascular disease compared with those in the lowest quartile of uric acid. The multivariate adjusted odds ratios(ORs) [95% confidence intervals(CIs)] for the highest quartiles for high Framingham risk were 3.00(2.00-4.50) in men and 2.95(1.08-8.43) in women. The multivariate adjusted ORs(95% CIs) for the highest quartile for high ASCVD risk were 1.93(1.17-3.17) in men and 4.53(2.57-7.98) in women. Conclusion Serum uric acid level is associated with an increased risk of prevalent obesity, hypertension, dyslipidemia, 10-year Framingham risk for coronary heart disease, and 10-year risk for ASCVD among Chinese adults without diabetes.
文摘Background: Serum uric acid (SUA) has been correlated with cardiac morbidity and mortality. However, its prognostic value in acute ST-segment elevation myocardial infarction (STEMI) is still uncertain. The aim of this study was to evaluate the prognostic value of SUA on admission in patients with STEMI undergoing primary percutaneous coronary intervention (PPCI). Methods: We prospectively enrolled 150 STEMI patients underwent PPCI. The mean age of the studied population was 56.1 years, 78%?were males?while 22% were females. Patients were divided into tertiles based on the basal serum uric acid level. Patients with high SUA (n = 72) was defined as a value in the third tertile (>6.4 mg/dl), and a low SUA group (n = 78) was set as a value in the lower two tertiles ( Results: SUA level on admission carried prognostic value in patients with STEMI undergoing PPCI where the low uric acid group had better KILLIP class (P =0.001), better TIMI flow (P = 0.001), higher ejection fraction (49.53 ± 8.75 versus 39.95 ± 7.06;P =0.001), better survival and lower incidence of other major adverse cardiac events (MACE) (P = 0.01) during the hospital stay and three months follow up?than the high uric acid group. Age, SUA > 6 mg/dl, TIMI flow, Killip class and EF 40% were independent predictors for MACE in such patients. Conclusions: High SUA level on admission was associated with higher frequency of in-hospital and three months follow up MACE in patients with acute STEMI undergoing PPCI.
